LIQUID-PISTOL.

Application filed May 28, 1919.

To all whom it may concern:

Be it known that I, DAVID HEYMAN, a citizen of the United States,residing at New York city, in the county and State of New York, haveinvented certain new and useful Improvements in Liquid-Pistols, of whichthe following is a specification.

My invention relates to an improved liquid pistol which may be operatedto eject successive quantities from a body of liquid, thus providingwhat may be termed a repeating istol.

One 0 the characteristic features and objects of the present inventionconsists in the utilization of the barrel as the reservoir for receivingthe liquid to be ejected. So far as I am aware, in the construction ofliquid pistols, it has heretofore been customary to employ a separatecell as a liquid reservoir, but constructions of this kind entailcertain manufacturing disadvantages which are obviated by my inventionwherein the barrel itself forms the liquid receptacle.

Another feature and ob ect of the invention is the simplification of themechanism for ejecting the liquid, thus reducing the number of parts andthe cost of manufacture to a minimum.

Two forms of the invention are illustratively exemplified in theaccompanying drawing, in which Figure 1 is a side elevational viewpartly in section of one form of the invention;

Fig. 2 is a sectional elevational view of a portion of the means foroperating the pluner; g Fig. 3 is a perspective view of a rocking frameor yoke used in the actuation of the plunger;

Fig. 4 is a side elevational view partly in section of a modified formof the invention; and

Fig. 5 is a perspective view showing the manner in which the modifiedform of the invention is employed.

In both forms of the invention shown in the drawing the barrel itselfforms the reservoir for the liquid, and the difl'erence between the twoforms lies in the operating means for the plunger.

Referring to Figs. 1 to 3 of the drawing, 10 denotes the handle or stockwhich is preferably formed integrally with what may 'be termed thebreech, these two parts Specification of Letters Patent.

being arranged substantially at right angles to each other. Held in theforward part of the breech 11 is a barrel 12 which constitutes theliquid reservoir. In the front wall of the barrel 12 is a small opening13 which serves both for the admission of liquid to and the ejection ofthe same from the barrel 12.

Operable in the barrel 12 is a plunger 14 carried at the forward end ofa plunger rod 15, the rear end of which is provided with a stud 16,projecting througha slot 17 in the upper face of the breech 11.

Carried loosely on the plunger rod 15 is a three sided frame comprisingthe front wall 18 and the side walls 19. Formed in the front wall 18 isan orifice 20 through which the plunger rod 15 passes. The frame is heldin biased contact with the plunger rod, as clearly shown in Fig. 2, bymeans of springs 21 and 22, the former being attached at one end to across pin 23 which extends through slots 24 near the upper edges of theside walls 19, and the latter spring having one end engaging the hole 25near the lower edge of the front wall 18. The rear ends of both springs21 and 22 are secured to the studs 26 and 27, respectively, near therear end of the breech 11, the stud 26 being positioned fartherrearwardly than the stud 27.

Fulcrumed on the pin 28 extending through the body of the frame is atrigger 29 the upper portion of which is forked and the arms of whichextend at opposite sides of the outer walls 19 of the frame and areorificed near the top so as to engage the pin 23.

The operation of this form of the device is substantially as follows:Assuming the barrel 12 to be filled with liquid, the ejection of thelatter in successive quantities is effected by repeated pressure on thelower end of the trigger 29. The springs 21 and 22 normally hold theframe 18, 19 in the biased position shown in Figs. 1 and 2 in which thewall of the orifice 20 rather lightly engages the plunger rod 15. Bypressing the trigger 29 the upper edge 20* and the lower edge sure thespring 21 which is under greater tension than the spring 22 tends torelieve the tight or positive engagement between the frame 18, 19 andthe plunger rod and convert such positive engagement into a looseengagement. When the plunger 14 has reached the extreme forward positionin the barrel 12 the liquid contained in the latter has been ejected anda fresh supply of liquid may be drawn into the barrel 12 by retractingthe plunger 14 through the medium of the upstanding stud 16.

In the modified form of Figs. 4 and 5, 12 denotes the barrel, 10 thestock or handle, and 11 the breech. 29 is a trigger which in this formof the invention is a dummy merely. Movable in the barrel 12 is aplunger 14 having attached thereto the plunger rod 15. Formed in theside of the breech 11 is an elongated slot 17" through which projects apin 16 extending from and substantially at right angles to the plungerrod 15. In the modified form of the invention the entire plungeroperation is effected through the medium of the pin 16. The operation isshown in Fig. 5-. The pistol is grasped in the hand with the index ngerrestin on the trigger 29 and the thumb engaging the pin 16. Byconstantly or intermittently pressing the pin 16 forward the plunger rod14 is forced forward in the barrel 12 and liquid is ejected through thefront orifice 13. When all liquid has been ejected a fresh supply may bedrawn in by simply moving the pin 16 rearwardly in the slot 17, thusretracting the plun er 14 and drawing liquid in through t e opening 13by suction.

\Vhat I claim is 1. A liquid pistol comprising a barrel, a plungerreciprocable therein, a plunger rod connected to said plunger, a frameloosely engaging said plunger rod, means adapted to cause a positiveengagement of said frame with said plunger rod and means to advance theframe.

2. A liquid pistol comprising a barrel, a plunger reciprocable therein,a plunger rod extending from said plunger, a frame through which saidplunger rod passes, springs for holding said frame in biased contactwith said plunger rod, and a trigger for moving said frame into positiveengagement with said plunger rod and advancing said plunger rod.

In testimony whereof I have affixed my signature in presence of twowitnesses.
